Abstract
The utility model relates to an AT (Advanced Technology) power supply type SF6 (sulfur hexafluoride) gas-insulated traction transformer, which belongs to the technical field of transformers. In the technical scheme, the transformer comprises a gas tank (1), coils (8), body insulations (9), a core (10), leads (7), coolers (6), a temperature controller (4), a body gas densimeter (3) and a burst pressure relay (5); and the temperature controller, the body gas densimeter and the burst pressure relay server as safety protectors of the transformer to monitor the temperature, pressure and the like of the transformer in real time. In the technique of the utility model, winding pairs, which generate main fluxes on each limb in the same direction and of which the two leakage groups are counteracted by each other, are formed, and thereby the requirement for low impedance is realized within the limited height of windings; and since the transformer adopts the heat-dissipating method of SF6 gas-circulating cooling, the transformer meets the high requirement for fire prevention, and also meets the condition of a narrow occupied floor area, and on the whole, the transformer has high economic and social benefits.
